fix: resolve all ESLint errors (lint now exits 0)

- useAppKeyboard: move all logic inside useEffect, fixes refs-in-render
  and no-unused-expressions for view mode shortcut handler
- SettingsPanel: refactor to inner component to fix setState-in-effect;
  remove unused maskKey function
- NoteList: remove re-exports (consumers import from noteListHelpers directly);
  fix no-unused-expressions in toggleGroup; eslint-disable for Icon-in-render
- useNoteActions: eslint-disable tabsRef.current assignment (valid pattern)
- Test files: fix no-explicit-any in useKeyboardNavigation, useSettings,
  useVaultLoader, wikilinks tests; update NoteList.test import path
